HANDLE AND PHONE ATTACHMENT FOR OPERA-GLASSES.

SPECIFICATION forming part of Letters Patent No. 574,125, dated December29, 1896.

Application filed December 16, 1895. serial No. 572,269. (No model.)Patented in France February 7, 1896, No. 253,778.

To aZZ whom it may concern.-

Be it known that I, GEORGE J. \VAIN- WRIGHT, of New York, in the countyand State of New York, have invented certain new and useful Improvementsin Phone Attachments for Opera-Glasses, (for which I have obtainedLetters Patent in France, dated February 7, 1896, No. 253,778,) and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

This invention relates to certain improvements in phone attachments foropera-glasses and the like.

The invention consists in a simple and inexpensive phone made insections and telescopically joined, provided at its lower end with asound-wave-receiving chamber and at its upper end with atransmitting-chamber through which the sound is transmitted by asuitable tube to the car, so that the volume of sound is controlled,intensified, and regulated by the elongation of the sections, so thatpersons of varying degrees of deafness may use the same instrument andadjust it to suit their hearing or the distance to be heard from.

The invention further consists in certain novel features of constructionand in combinations and arrangements of parts more fully describedhereinafter and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevation ofthe complete device, and Fig. 2 is a longitudinal section thereof.

Like letters of reference mark the same parts throughout the views.

(L is the usual opera, field, or marine glass, made in telescopicsections and provided with the ordinary adjusting means I) and thelenses 0 o.

d indicates a hollow support or phone permanently closed at its upperand lower end. This phone is made in telescopic sections, as shown, sothat its length can be increased or diminished at will. The uppersection 6 at its lower end is provided with outwardly-extendingprojections or lugs f f, so that when said section reaches its limit ofupward movement the lugs or projections ff will bear against theshoulders g g, formed by the upper edges of the lower section beingturned inwardly, so as to prevent the upper section being entirelywithdrawn. provided near its top with spring clampingarms, (shown indotted lines,) adapted to embrace the barrel of the opera-glass, thelower arm being provided with an auxiliary strengthening-arm h, which,after being inserted under the cross-bar 2', acts as a brace insupporting the glass.

j indicates a section of tube opening into the hollow upper section at apoint directly below the upper closed portion thereof. The inner openend of this section of tube enters the sourid-collecting chamber 7;,here shown as an inverted cone, this cone-shaped soundcollecting chamberbeing formed on the interior of the upper section of the hollow supportdirectly below the closed end thereof.

Z is the sound-conveying tube, one .end of which is suitably connectedwith the section of tube j, so as to be freely movable at that point,the object being to have this tube so connected that it can be turned inany direction desired to accommodate a right or left hand person oreither defective ear.

m indicates the ear piece or tube.

"a n are the sound-receiving openings or perforations, preferablylocated on one side of and above the closed bottom of the hollow lowersection d.

The operation of my device is as follows: Supposing a person to be ofdefective hearing or having a back seat in a place of amusement orelsewhere and he desires not only to hear what is going on upon thestage, but also to obtain a good view, the phone is attached to theglass and the glass raised to the eyes and the tube at inserted ineither ear. The sound-waves on entering the openings a pass up throughthe hollow phone-sections which form the receiving instrument and aroundthe inverted cone-shaped sound-collecting chamber 7.1. They then come incontact with the dome or closed end of the upper section The support isof the phone. After coming in contact with the inner surface of saiddome the soundwaves are deflected against the walls of the interior ofthe inverted-cone-sliaped soun(1 collecting chamber k, the same therebyforming a transmitter, as such sound waves after striking said wallsWill enter the tube-section communicating with the tube Z, and willconvey the sound to the ears of the person using the device.

It is evident that the phone attachment forming the sound conveying andtransmitting instrument can be used independent of the opera or fieldglass, and that various changes might be made in the forms,constructions, and arrangements of the parts described without departingfrom the spirit and scope of my invention. Hence I do not wish to limitmyself to the exact construction herein set forth, but consider myselfentitled to all such changes as may fall Within the spirit and scope ofmy invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of theUnited States, is-

l. A handle for opera-glasses forming an ear-trumpet comprising asound-receiver in its lower portion, a sound collector and transmitterin its upper portion, ear attachments, and a clamp to embrace the barrelof the glasses, as set forth.

2. An attachment for opera or like glasses comprising a handle made intelescopic sections and adapted to be used as an ear-trumpet, saidhandle being provided with a clamp to grip the barrel of said glass andhaving a reversible support whereby either hand may be used to hold theglass to the eye substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
